Buyer's Guide: Aquarium Test Kit

What Type of Aquarium Test Kit is Best For Your Fish?

The best aquarium test kits are indispensable tools that any aquarist should own. They assist you in accurately measuring the condition of your aquarium, and also make quick changes when necessary. Without this critical information, you'd have no means of determining if your aquarium is still healthy or not. A simple kit will contain a few components, which you then use to gauge the condition of the water in your aquarium. You'll be able to tell whether or not there is ammonia present, nitrite and nitrate levels, water clarity, and even the presence of goldfish. There are a number of kits available on the market, but before you buy, make sure you know what exactly it is you're looking for.

You might think that it's difficult to find the best aquarium water test kits. After all, they're not widely advertised, so you might not see many ads for them. This could actually work in your favor, because some brands actually do provide the best service. If they have good reviews from happy customers, then this could be a good indication of the quality of their product.

Aquarium test kits that use the Nemo system are one example of quality kits. These particular kits have been proven to be highly effective in testing both pH and ammonia parameters. In addition to being extremely accurate, they are also very convenient. They can usually be used together with a pH calculator, so you can determine your fish's ph level right away. These tetra kit tests are sold for around $40, and they are very useful.

Aquarium test tubes are another thing that any serious aquarist should have around. There's nothing worse than having to randomly select a tube to try, only to find out that it doesn't work. Of course, there's nothing fun about getting something useless as well. However, random selection is not an option for many people, who would much rather have a kit with a built-in error-checking and measuring mechanism. These test tubes are designed for use with Aquascape's EZ Aquarium Thermometer.

For people who want to skip the trial-and-error method of selecting a test kit, there are plenty of automated options available. Automatic pH and ammonia testing kits can come in different models. Some of these simply have a few basic features like an adjustable pH level, an alarm, and a timer. Other models include more advanced features, such as indicators for over or undercharging. The pros and cons of each type of automated aquarium testing system will depend upon how accurately you need the results, how much time you want to spend, and what features you find most useful.

Most automatic pH and ammonia levels self-calculate their readings based on reading from the parameters set by you. Some even allow users to enter information about tank conditions, such as current lighting and water hardness. There are even some API tests that come equipped with a color chart. Using a color chart makes it easy to monitor the fish's progress over time.

As far as accuracy goes, the only sure thing is that test kits come with detailed instructions on how to interpret the data they return. However, most users find that the instructions do not go into depth enough to explain why things are accurate, or why accuracy can fluctuate. Before spending your money on expensive Aquascape test kits, try out one or two with an additional pH or ammonia tester. If they give you consistent results, then you're probably on the right track.

Unfortunately, no test can determine what type of marine aquarium water you have. This is a job best left to the experts. It's also a job the aquascape hobbyists perform, so there's no reason to guess at your base pH or ammonia levels. Just buy a test kit, follow the directions, and test the results. You'll soon know whether or not you need to use additives.
